Cells Of The Nervous System (Basic Of Neurons)

Heya bloggers!

Nearly 2 weeks I haven’t written about Psychology article; after busy writing reviews and renovating some features on my blog --- now, I’m back again! Yeay!

Today’s topic is about nervous system; before I go to the main topic, I will write the introduction of neurons which the most important part of knowledge you must know to understand how the nervous system work in your body, particularly in your brain. The introduction will contain about chemistry, biology, and slight bit science knowledge; therefore prepare your brain ready for this!

Cells Body or Soma

The very basic of knowledge you must know is to know about what type of cells in neurons. You can see the form of the neurons from the picture below.

The structure of neurons itself have different functions. The two of important cells that taking part in the nervous system calls Neurons and Glia. These nerve cells are specialised for communication through a message.

Alright, before I go further; understanding about the neuron structure is very important to know how these cells work and communicate with each others.

Soma; As you see on the picture of the Neuron’s form; soma contains the nucleus and much of the machinery that provides for the life process of the cell e.g. mitochondria, lysomes, golgi bodies. The nucleus itself contains the genetic code; and other things all cells have.

Dendrites; Dendrites derive from Greek word, which means Dendron or tree. Dendrites located outside of the cell body (see the picture); through dendrite neurons receive electrical signals from other nueorons.

Axon; Axon often covered by myelin sheat that carries info away from cell body to terminal buttons.

Node of ranvier; The task of node of ranvier is to make the message travel faster.

I think that’s enough for the basic information of the neuron structure. You will understand furthermore when you use to with those words by knowing and understanding each function of neurons. 

Neurons function can be classified into 3 classifications:

Sensory neurons; carry message from the senses to the brain by detecting the changes in the environment.

Motor Neurons; carry message to the muscles and control movement. They also control the secretion of glands.

InterNeurons; the task is to connect cells; act as a link between sensory neurons and motor neurons.

What you must know as well is that neurons the wiring of the nervous system that make up half of the volume of the brain. Also they receive info from on average tens of thousands of other neurons. The neurons receive info from several different sources by integrating and transform the signals. Complex output signals may occur as signals distributed to many other cells.

Happy weekend everyone!
